Ferrocene end-capped palladium(II) and platinum(II) complexes with thiophene spacers

A series of heterobimetallics containing ferrocene and Pd(II) or Pt(II) have been synthesized by oxidative addition of ferrocene-substituted halothiophenes with zerovalent palladium or platinum precursors. The stable solids were thoroughly characterized by elemental analysis, NMR, UV-vis spectroscopy, and cyclic voltammetry. The rich redox chemistry of the complexes depends on the conjugation length that separates the two metal sites. The crystal structure of a platinum sigma-thienyl complex, (C5H5)Fe(C5H4CH=CH-th-Pt(PPh 3)2(Br)) (th = 2,5-disubstituted thiophene) has been determined.

The reactions of mono(cyclopentadienyl)titanium(IV) trichloride with a new class of Schiff bases (H2L), derived by condensing 1,1?-diacetylferrocene with different 3-substituted phenyl-4-amino-5- mercapto-1,2,4-triazoIes, have been studied both by a conventional stirring method and also using microwave technology. Binuclear products of type [{eta5-C5H5)TiCl2}2 (L)] have been isolated in both cases. Tentative structural conclusions are drawn for the reaction products based upon analysis, electrical conductance, magnetic moment and spectral (UV-Visible, IR, 1H NMR and 13C NMR) data. FAB mass spectra of complexes were also recorded to confirm the binuclear structures. Studies were conducted to assess the growth inhibiting potential of the ligands and complexes against various fungal and bacterial strains.

Ferrocenylmethylphosphonate formation. Synthesis, spectroscopy and molecular structure

Reaction of ferrocenylmethanol, FcCH2OH, with beta-cyano-N,N-diisopropyl chlorophosphoramidite in dichloromethane yields the ferrocenylmethylphosphonate derivative, FcCH2P(O)(N(iPr)2)(OCH2CH2CN), 2a. The crystal and molecular structure of 2a is presented. 31P NMR data suggest that this is formed from FcCH2OP(N(iPr)2)(OCH2CH2CN) via a Michaelis-Arbusov-type rearrangement. Similar behaviour was also observed for 1,2-phenylene chlorophosphite and diethyl chlorophosphite.

Development of a miniaturized injection cell for online electrochemistry?capillary electrophoresis?mass spectrometry

Abstract: The elucidation of oxidation or reduction pathways is important for the electrochemical characterization of compounds of interest. In this context, hyphenation of electrochemistry and mass spectrometry is frequently applied to identify products of electrochemical reactions. In this contribution, the development of a novel miniaturized injection cell for online electrochemistry?capillary electrophoresis?mass spectrometry (EC?CE?MS) is presented. It is based on disposable thin-film electrodes, which allow for high flexibility and fast replacement of electrode materials. Thus, high costs and time-consuming maintenance procedures can be avoided, which makes this approach interesting for routine applications. The cell was designed to be suitable for investigations in aqueous and particularly non-aqueous solutions making it a universal tool for a broad range of analytical problems. EC?CE?MS measurements of different ferrocene derivatives in non-aqueous solutions were carried out to characterize the cell. Oxidation products of ferrocene and ferrocenemethanol were electrochemically generated and could be separated from the decamethylferricenium cation. The importance of fast CE?MS analysis of instable oxidation products was demonstrated by evaluating the signal of the ferriceniummethanol cation depending on the time gap between electrochemical generation and detection. Graphical abstract: [Figure not available: see fulltext.].

Reactions of a cationic geminal Zr+/P pair with small molecules

The metallocene cation complex [Cp*2ZrCH3] +[B(C6F5)4]- inserts the phosphino-substituted alkyne Ph-Ci – 1/4C-PPh2 into the [Zr]-CH3 bond to form the internally phosphane-stabilized cation [Cp*2Zr-C(=CMePh)PPh2]+ (10). Complex 10 adds alkyl isocyanides as well as pivalonitrile at a lateral site at the bent metallocene wedge with retention of the Zr-P bond. Complex 10 acts as a reactive frustrated Lewis pair toward heterocumulenes, undergoing Zr+/P addition reactions to the carbonyl groups of an alkyl isocyanate and of carbon dioxide to form the respective five-membered metallaheterocyclic adducts 13 and 14. With mesityl azide complex 10 undergoes a Zr+/P FLP N,N-addition reaction at the terminal azide nitrogen atom to form the four-membered FLP cycloadduct 15. The Zr+/P FLP is a reactive hydrogen activator. In a stoichiometric reaction it generates a hydridozirconocene cation that subsequently serves as a hydrogenation catalyst for various olefinic or acetylenic substrates. The Zr+/P pair 10 undergoes selective 1,4-addition reactions to conjugated enones and to a conjugated ynone to give the corresponding seven-membered metallacyclic Zr+/P FLP addition products. Many compounds of this study were characterized by X-ray diffraction.
